well, I have an 02-03 r1 tank that I can swap right over with only needing to bolt a bracket on.
the tank just leaves a gap between the tank and frame which I could easily fill.
and I have 2 04-06 r1 tanks that will need much modding.
the under part that sits into the frame is too wide so I need to do alot of hammering.
if I have a grinder and welder then I could easily do this mod.
02-03 r1 tank
04-06 r1 tank.
Iv already starting the hammering on this tank
you can see how much farther I need to go down. about an inch.
I like the blue and yellow
put this tank in crooked so you could kinda see what it will look like when it mates to the frame...also had to take an awkward angle pic

.
no tank!

dirty carbon fiber
The last thing Im going to need to do after the tank swap, is raise the tail higher.
the advise I was looking for, is what tank should I use?
or should I fiberglass a 04-06 tank fairing and just use that just like crazyc did on his fzr1000 fighter.
